A NOVEL FINITE-ELEMENT METHOD FOR MOVING CONDUCTOR EDDY-CURRENT PROBLEMS

A novel finite element method, as an alternative to upwinding, is prop osed based on the elimination of the factors which could cause numeric al oscillation and instability by properly choosing a set of unconvent ional weighting functions. The proposed method is first developed and verified for a one dimensional case and then extended to two dimension al problems. The calculation results for a 2D problem, along with the exact solutions and those obtained from Galerkin's and ''optimal' upwi nding methods, show that the proposed method is superior to the other two methods in terms of accuracy and freedom from oscillation.
